I have a 2012 CT200h premium and I can't figure out this damn sunroof rattle for nothing. It only happens when it's closed all the way. I've read and read and read and nothing seems similar to this. It just has a weird rattle that's hard to explain. If you push up on the sunroof glass while it's closed it won't rattle. I've tried putting sticky felt on the sides of the metal body sunroof surround and I thought that had cured it, but it comes back! So I reapply more felt, remove old, etc.. and it still comes back. It's not the bar that raises when the sunroof opens as I can hold that down and it still rattles. It's enough to make me hate this car. I don't know what else to try. I'm out of warranty and just hit 50,000 miles. I can't seem to find anything online to try and I'm not prepared to remove the headliner to fish for something.

Any suggestions?

I have the same damn issue. My 2014 F sport CT200h rattles like crazy now at 32K miles. Any ideas?

2013 CT. Had the same rattling noise just after 10k miles. Under the warranty Managed to replace the whole sunroof. Noiseless for 6 months. The rattling is back. Louder. Any suggestions? Please.

I had the same problem on my 2nd CT, a 2013 model that I'd purchased used), and nothing I could do by myself seemed to help. Since I'm severely allergic to rattles, I had the dealer take a look when I took the car in for scheduled maintenance and they told me it was due to the rubber gasket in the roof being partially torn. A mere $500 later (part and labor)and the sunroof was silent once again.

My sunroof is quiet, it's the shade that is noisy. When it's open it rattles like crazy, when I close it, the rattle goes away. I listen to my stereo pretty loud most of the time so it's not a big deal but it's annoying.

It seems there is no solution for sunroof rattling. There is a video on you tube that the guy used pieces of foams in order to push the sunroof up when closed to stop the rattle but I am not sure if that will cause leakage in rain or not.

I actually thought my rattle was from the shade as well - i even told the dealer I thought the shade was the cause when I dropped the car off. They said it was the gasket, gave me the old part (which was obviously worn out and had been deformed). All I can tell you is that the unbelievably annoying rattle was gone and hasn't come back.

I use to have this issue with my old Infiniti G35 and use to drive me nuts. They said it was also a worn gasket, but it never really resolved the issue. Finding a CT with no sunroof was actually a plus!

When mine starts to rattle, I just open and close the sunroof, and then it's quiet for another month or two 🤷‍♂️

I was dead wrong. The sunroof shade just muted the noise, the cause was indeed the weather seal. But I didn't replace mine, I just cleaned it really well. I used Aerospace 303, although I suspect you could use Armorall or anything safe for rubber that cleans well. I am amazed at the difference!

How difficult was it to do the job yourself? I actually totalled the original Ct with the sunroof rattle shortly after spending $500 at the dealer. I purchased
a nicer replacement with lower miles soon after and now the sunroof rattles on the new one. If I can save the cash by doing it myself that would be awesome.

You don't have to take the gasket off, you literally just open the sunroof and wipe it clean all the way around with a towellete. Takes 5 minutes. Actually i did it twice after it dried the first time just to make sure it was super clean, so maybe 10 minutes. Immediate difference.
